[0037] In order to make the objectives, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be described below in connection with the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments of the present application. The components of the embodiments of the present application described and shown in the accompanying drawings herein can be arranged and designed in various different configurations. Therefore, the following detailed description of the embodiments of the present application provided in the accompanying drawings is not intended to limit the scope of the claimed present application, but only represents selected embodiments of the present application. Based on the embodiments of the present application, all other embodiments obtained by those skilled in the art without creative work fall within the scope of protection of the present application.

[0038] In the related art, an artist uses a digital asset production software to place a hair plug model on a model surface and render a separate material, with defects as follows: first, the artistic production process is complex, the industrial production and iteration cycle is long, resulting in extremely high production cost; second, the flexibility is poor, and it is impossible to dynamically adjust according to platform performance, detail level, etc., resulting in performance waste; third, the effect is not ideal, and it is difficult to express the messy, dense and fine fur effect of animals.

[0039] In addition, the runtime renders the model stack multiple times, each time moving the vertices along the normal direction by a distance, and in combination with pixel-level clipping, the technical solution of stacking the shape of the hair is defective in that: first, the effect is not ideal, and there are faults in the performance, and the hair disappears when viewed from the side; second, the rendering efficiency is low, the number of vertices is huge, and a large number of pixels are discarded, causing great performance waste.

[0040] In addition, the above two hair rendering schemes also do not solve the physical performance, shadow rendering, production process, and the like of the target object, and therefore, the rendering scheme in the related art is not applicable to real-time rendering of mobile platform games.

[0041] The embodiments of the present application can be applied to the scene of real-time rendering of mobile platform games, and specifically, the animal hair in the scene can be rendered, including real-time hair rendering of a mobile terminal, hair animation support, and physical simulation of hair.

[0042] The following illustrates a specific implementation of a real-time rendering method provided by some embodiments of the present application by taking a mobile device as an example. It can be understood that the execution subject of the embodiments of the present application can be any electronic device capable of running the method, which can be a computer, a tablet computer, and the like, and the above mobile device is only an example, and the present application does not limit this.

[0043] At least to solve the problems in the background art, as Figure 1 illustrated, some embodiments of the present application provide a method for efficient real-time game image rendering, which includes:

[0044] S110, using a patch to establish the outer hair of the target object in the to-be-rendered picture, and using a shell to establish the bottom fur of the target object.

[0045] Specifically, a patch perpendicular to the normal direction of the surface of each edge of the target object is generated, and the patch is used to establish the outer hair of the target object in the to-be-rendered picture.

[0046] That is, as Figures 2-5 illustrated, the original model of the target object in the to-be-rendered picture can be as Figure 2 illustrated, for example, Figure 2 may be a bird without rendered feathers, based on Figure 2 each edge of the original model as illustrated in the original model, each edge of the original model is first confirmed, and then a patch perpendicular to the surface normal direction on each edge is established, to obtain a patch model as Figure 3 illustrated, the hair of the target object is established based on the patch model.

[0047] After obtaining the patch model, the long and thick outer layer guard hairs of the target object in the picture to be rendered are established by using the patch, and the outer layer hairs are as shown in Figure 4 It can be understood that the length of the outer layer hairs can be greater than the length of the bottom layer down hairs, and the top points are moved along the normal direction by a distance by using the shell to stack, to obtain the disordered and thin bottom layer down hairs of the target object close to the skin as shown in Figure 5

[0048] Therefore, by rendering the outer layer hairs and the bottom layer down hairs of the target object, the embodiment of the present application can simulate the animal hairs realistically, and combines the advantages of the patch and the shell, to improve the reality of rendering.

[0049] As a specific embodiment of the present application, the vertex information of the target object includes: a vertex ID, an X channel of a vertex texture map coordinate, and a Y channel of the vertex texture map coordinate.

[0050] That is, the embodiment of the present application optimizes the bandwidth occupation while integrating the rendering, animation and physical simulation steps. That is, each drawing step uses a specific pre-generated model for drawing. Since the position, vector and physical information of the hair vertex are baked into the map in advance, only the minimum vertex information needs to be retained on the pre-generated model.

[0051] The patch model for drawing needs to determine the vertex position, the vertex color and the triangle index:

[0052] The vertex position includes: an X channel (that is, a vertex ID, used to identify the position of the vertex corresponding to the vertex information graph), a Y channel (that is, an X channel of a vertex texture map coordinate, used for main texture sampling) and a Z channel (that is, a Y channel of a vertex texture map coordinate, used for main texture sampling).

[0053] The vertex color includes: an R channel (that is, a current hair layer ID), a G channel (that is, a total number of current hair layers), a B channel (that is, a transition value of a current hair layer (gradual change from hair root 0 to hair tip 1)) and an A channel (not used, reserved).

[0054] The triangle index includes: a triangle number.

[0055] The model for drawing the shell needs to determine the vertex position and the triangle index:

[0056] The vertex position includes: an X channel (that is, a vertex ID, used to identify the position of the vertex corresponding to the vertex information graph), a Y channel (that is, an X channel of a vertex texture map coordinate, used for main texture sampling) and a Z channel (that is, a Y channel of a vertex texture map coordinate, used for main texture sampling).

[0057] ​The triangle index includes: triangle number.

[0058] Therefore, by the above embodiment, the GPU does not need to load useless data (such as normal, tangent, model space position, etc.) when binding the model, which can greatly reduce the bandwidth occupation, and has a significant effect on reducing the memory occupation, heat and power consumption.

[0059] S120, obtaining the hair root vertex information of the outer layer hair and the bottom layer fluff according to the vertex baked model.

[0060] It can be understood that the vertex baked model is composed of N triangles, N is the number of vertices of the target object, and one triangle corresponds to one pixel of the map.

[0061] In an embodiment of the present application, the specific execution steps of S120 include: first, calculating the vertex animation in the rendering process and writing the position of the target object in the vertex baked model into the corresponding pixel point, then calculating the vertex animation and writing the normal and tangent information of the vertex of the target object in the vertex baked model into the corresponding pixel point to obtain the hair root vertex information.

[0062] That is, in order to enable the hair of the target object to follow the surface movement of the model, wherein the movement includes overall displacement, rotation, scaling and animation deformation, and is compatible with mobile platforms, the present application uses a special way to bake the vertex position of each frame, which specifically includes:

[0063] A vertex baked model is pre-baked, and for each vertex of the original model of the target object in the vertex baked model, there is a triangle, that is, there are N triangles for N vertices, and the three vertices of the triangle store the vertex information of the original model of the target object.

[0064] In the running process, the above-mentioned vertex baked model is rendered twice every frame, wherein each triangle corresponds to one pixel of the map, that is, each map only needs a small size (for example, only 128x64 for mobile terminals), so as to occupy less bandwidth. In the first rendering process, after calculating the vertex animation, the local space position is written into the corresponding pixel of the screen to obtain the first map, and in the second rendering process, after calculating the vertex animation, the normal and tangent information of the vertex is written into the corresponding pixel to obtain the second map. When rendering the hair, the first map and the second map are read as the hair root vertex information.

[0065] It can be understood that the hair root is the end close to the skin in the animal hair.

[0066] Therefore, by twice rendering, the embodiments of the present application can ensure that the pixel points corresponding to the target object include accurate data, thereby improving the rendering accuracy.

[0067] S130, generating each position from the hair root to the hair top according to the hair root vertex information and the position of the virtual particle, and corresponding each position to the corresponding pixel on the screen, rasterizing the pixel to obtain a target rendering image.

[0068] In an embodiment of the present application, the specific implementation steps of S130 are as follows:

[0069] S1301: determining the position of the virtual particle corresponding to each vertex included in the target object.

[0070] It should be noted that the virtual particle is arranged on the target object, and the position of the virtual particle includes the position information of the current frame and the position information of the last frame.

[0071] That is, because the range of the world map is too extensive, if the world map is used in the rendering process, a large amount of calculation and inaccurate positioning may occur. Therefore, the position of the virtual particle is used as a reference point in the present application, and the position of the virtual particle is placed on the target object. Using the position of the virtual particle as a reference point in the process of calculating the vertex can reduce the amount of calculation, and because the position of the virtual particle is relatively close to the position of each vertex of the target object, the positioning is relatively accurate.

[0072] For example, if the target object is a bird, the position of the virtual particle can be the beak or the eye. The above examples are only examples, and the present application is not limited thereto.

[0073] Therefore, by setting the virtual particle, the present application embodiment can reduce the amount of positioning data, and by setting the virtual particle on the target object, the amount of calculation can be reduced to ensure the rendering efficiency.

[0074] S1302: rendering the position map of each vertex corresponding to the virtual particle, and updating the position of the particle and writing into the corresponding pixel.

[0075] That is, still using the vertex baking model for rendering the position map and the vector map in the above technical solution, a virtual particle is set for each vertex in the original model of the target object for subsequent physical simulation (including inertia, gravity and wind force) rendering, wherein each particle only needs to record the position information of the current and last frame. The vertex baking model is rendered once every frame at runtime, the particle position map is rendered, and the particle position is updated using the Verlet integration and written into the corresponding pixel.

[0076] It can be understood that the above-described updating of the position of the particle using the Verlet integration is only one embodiment of updating the position of the particle, and the present application is not limited thereto.

[0077] S1303: Interpolating the hair root vertex information and the position map of the virtual particle to obtain each position from the hair root to the hair top, wherein the interpolation is completed by a second-order Bezier curve.

[0078] That is, the position map of the particle is read when rendering the hair to affect the shape of the hair. According to the hair root vertex information and the position of the particle, each position of the hair from the hair root to the hair tip can be interpolated by a second-order Bezier curve, and each position also needs to be mapped to a corresponding pixel on the screen. The starting point of the Bezier curve is the hair root position, the end point of the Bezier curve is the particle position, and the control point of the Bezier curve is set as an external parameter by the user.

[0079] Therefore, the embodiment of the present application can accurately obtain each position from the hair root to the hair top by interpolating the hair root vertex information and the position map of the virtual particle, and can accurately render each position by generating each position from the hair root to the hair top, thereby improving the rendering accuracy.

[0080] S1304: Obtain parameters representing inertia, gravity and wind force, and then adjust each position by the parameters to obtain each target position.

[0081] That is, in order to ensure that the hair rendering is more realistic, the physical changes of the hair in the real world due to environmental influences need to be rendered. The change parameters of inertia, gravity and wind force need to be set in advance, and after obtaining each position from the hair root to the hair top, each position from the hair root to the hair top needs to be adjusted by these parameters, for example, after the target object accelerates and flies, each position from the hair root to the hair top still moves forward in the next frame after the current frame stops due to inertia.

[0082] It can be understood that the above-mentioned parameters of physical changes are only examples, and the present application does not limit this.

[0083] Therefore, the embodiment of the present application can simulate the swinging style of the hair of the target object during movement by adjusting and rendering each position by the parameters representing inertia, gravity and wind force, thereby improving the accuracy and reality of the rendering.

[0084] S1305: Map each target position to a corresponding pixel on the screen, and perform rasterization processing on the pixel to obtain a target rendering image.

[0085] That is, after obtaining each target position from the hair root to the hair top after the physical change adjustment, each target position is mapped to a corresponding pixel, and then the pixel is processed in color, gloss, etc. to obtain a target rendering image.

[0086] Therefore, based on the above-mentioned embodiments, the application has better rendering performance, that is, no fault feeling, and good plush feeling when viewed from the side; physical performance suitable for mobile terminals, that is, mobile terminals can also obtain real-time physical feedback when objects move, and even achieve real-time physical interaction with surrounding objects; higher production and iteration efficiency, that is, the process can be programmed and automated, and the user can observe the effect change in real time by one-key updating; better flexibility, that is, the number of hair layers drawn and the animation update frequency can be automatically adjusted according to platform performance and detail level, and performance grading can be better; high rendering efficiency suitable for mobile platforms, that is, the number of vertices and the number of triangular faces that need to be drawn are greatly reduced, and the bandwidth occupancy is improved compared with related technologies under the same performance.

[0087] The above describes a specific embodiment of a method for efficient real-time game image rendering, and the following will describe a method for efficient real-time game image rendering.
